By employing the latest technologies for Project ONE, INEOS is striving to keep the impact on the climate as low as possible.
By using the latest technologies, Project ONE’s ethane cracker will emit, on average, less than half of the CO2 than the best performing comparable installations in Europe. The hydrogen which is generated as a by-product during the ethylene production process is used as carbon-free fuel: hydrogen does not release any CO2 when burned. As a result we can significantly reduce the use of natural gas. Our record low footprint raises the bar for older, polluting installations (for example, via the European Union Emissions Trading System). Project ONE emits 0.29 tonnes of CO2 per tonne of product or just 43% of the current EU ETS benchmark value of 0.68 tonnes of CO2 per tonne of product. When Project ONE comes online, it will tighten the EU ETS benchmark value by around 14%. Steam crackers in the EU ETS system that do not meet this lower benchmark value will have to buy additional emission rights to cover emissions or take more emission reduction measures.
Buyers of the ethylene produced by Project ONE will save 2 million tonnes of CO2 per annum as they no longer need to rely on the ethylene from older and more polluting plants.
Also, the products made from ethylene will ultimately save twice as much CO2 as was necessary for their production – because they make end-products (e.g. cars) lighter and with longer lifetimes.
We’re also providing space on the Project ONE site for the collection of CO2. The current technology for capturing CO2 from flue gases is still very energy-intensive, and there is currently no network for discharging the collected CO2. We expect important technological breakthroughs in the near future that will make CO2 capture much more efficient. A study is currently being carried out to realize such a CO2 discharge infrastructure in the port of Antwerp. INEOS is working on this with other players from the port of Antwerp via the Antwerp@C consortium.
Project ONE guarantees very high energy-efficiency. The maximum recovery of heat and cold flows ensures lower energy consumption. For example, the cold energy of the cryogenic ethane supplied, and the heat of the furnaces of the ethane installations, will be reused elsewhere in the process and less external steam will have to be generated.
In the design of the ethane cracker, very ‘selective’ technologies have been chosen that contribute to a maximum conversion of the raw materials into high-quality chemicals. This results in a particularly high carbon-efficiency of almost 90% – which is much higher than in installations that use crude oil instead of ethane or propane. This means that barely 10% of the carbon present in the raw materials is converted into CO2, the remainder is converted into a high-quality chemical building block.
